Lucien Ortane is a Paragon in the Etherian Empire. His job is to explore the universe and spread Etherian doctrines of peace, justice, and immortality to sentient beings everywhere. Like all Paragons, and most citizens, Lucien believes that Etherus, the benevolent ruler of the Empire, is exactly who he claims to be: the one true God and creator of the universe.

But not everyone is a believer.

The Academy of Science circulates a petition to send a mission to the cosmic horizon and learn the true nature of the universe. Over a billion people sign it, and Etherus grants their request, but with a dire warning: evil is lurking in the dark.
